a. CH4 molecules interact more closely in the liquid than in the gas phase.
b. HF is a weak acid neutralized by NaOH.
c. Ice, H2O, has a solid structure with alternating H−O interactions.
d. H2Te has a higher boiling point than H2S.
e. HF has a higher boiling point than HCl.

Answer 1

c. Ice, H₂O, has a solid structure with alternating H−O interactions.

e. HF has a higher boiling point than HCl.

Step-by-step explanation:

For molecules to interact through hydrogen bonding, it is required that there is an H atom bonded to a more electronegative atom, such as N, O or F.

Select the interactions that can be explained by hydrogen bonding. Check all that apply.

a. CH₄ molecules interact more closely in the liquid than in the gas phase. NO. The electronegativity of C is not high enough to form hydrogen bondings.

b. HF is a weak acid neutralized by NaOH. NO. This reaction occurs in water and it is better explained by ion-ion forces.

c. Ice, H₂O, has a solid structure with alternating H−O interactions. YES. This structure is a consequence of the hydrogen bonding.

d. H₂Te has a higher boiling point than H₂S. NO. The electronegativities of Te and S are not high enough to form hydrogen bondings.

e. HF has a higher boiling point than HCl. YES. The stronger hydrogen bonding interactions in HF explain the higher boiling point.
